Abstract : Objective: The objective of the study was to investigate the effect of interplanting Chamaecrista rotundifolia on arthropod community in mango orchard, and to definite whether interplanting C. rotundifolia is benefit to control pests or not in mango orchard. Method: The composition and diversity of arthropod communities in the mango orchards with or without interplanting C. rotundifolia were investigated in Hui' an country, Fujian Province, China from April to September in 2008. Result: The results showed that 73 arthropod species belonging to 12 orders, 52 families in the interplanting orchards and 57 arthropod species belonging to 12 orders, 44 families of Insecta and Arachnoidea in the non-interplant orchard were collected. The dominant species in interplanting orchard were Monomorium chinensis and Tetramorium guineense which were predatory natural enemies, but the main dominant pests in non-interplanting orchard were Scirtothrips dorsalis and Orgyia postica which harm mango. The species richness and individual of total community and natural enemies were greater in the interplanting orchard than in the non-interplant orchard, but interplanting showed no significant effect on the other subcommunities. Conclusion: The results suggested that interplanting C. rotundifolia in mango orchard could increase the species and quantity of enemy insect and the quantity of neutral insect, and have a certain degree of benefit to control the arthropod community structure, which are helpful to integrated pest management in mango orchard.
